To all 'wfwm t may conce-m Be it known that We, hxrrnniv. CHAP- MAN and MARK C. CHAPMAN, citizens of the United States, residing at Aurora, in the county-ot Kane, State or' Illinois.y have invented certain new and useful linprovements in Deep-Tell Pumps, of which the following` is a sj'ieciication7 reference being had-to the accompanying drawings.

This invention relates to pumps for raising Water from deep irells. being a. division oi" our applicationg 482,517, which was filed on `lidarch l0, 1909,' upon which application Patent o. llelf was granted on August l0. 19M. lt is one of the objects of our in.- vention to provide a liquid balancing nieans in connection with the shaft of a rota ry deep well pump by which the shai't is adapted to be raised on' of its auxiliary bearings and rotatably sustained upon a iilrn of liquid escaping between oppositely-disposed parts of our balancing mechanism. lt is another obg'ect of our invention to provide an iinproved forni ci' balancing' mechanism in which the parts between which the `sustaining iilro of Water escapes have a fiat buttino; engagement whereby an;T Wear `which nia;v result in use can be compensated for by suitable adjust-ment of the parts. lt is another object oi our invention to provide neiv land improved forni or" coupling devices by which the several sections of the Well tube and shaft casing are connected together, and suitable bearings are prorided for the sha-ft. lt is another obj ect of our invention to provide ay new and improved arranger/nent of ivell tube., sha-ft casing, sha-ft, runner, and auxiliary anti-'friction bearing for the upper end of the sha'tby Which the shaft may be tightened and straightened relative to the shaft casin andthe Well tube. lt is another object of our invention to improve devices of this type. in sundry details hereinafter pointed out. The preferred rneansby which :we have accomplished our several( objects are illustrate-d inthe accompanying drawingsv and are hereinafter speciicallv described. rliat which ive believe to be new 'and desire to cover by* this application is set forth. in the claims.

Reterring to the several ligijures .of the drawings in which correspondinoj parts arel indicated by the reference characters,-

1G indicates a etant-.ard having' laterally" projecting. lugs ll oil-Which rests a casting l2 which carries the auxiliar7 bearing means hereinafter described tor supportingq the sliait together with means for lubricating such bearings. shaft 13 is connected by means. ot a coupling: device le of any suitable type with a motor l5 supported by the standard l0. The auxiliarv bearings comprise a casino; 16 mounted b v means of screw-threads upon the upper end of the casting' i2. a. 'set-screw i7 being' provided .tor locking the casing` 16 in the desired adjusted position relative to the casting l2. rlhe casing;r 1G supports an antifriction bearing 18 of any suitable type7 which underlies a collar 19 adjustabljv lined b v ineans of set-screws upon the shaft i3.

in anti-friction bearing' 2() is mounted upon the shaft 13 below the casting 12.. a collar 2l.

being' adiustablv mounted upon the shaft 13 in engagement with the bearingr Q0., the arrangement beingr'sucli that the bearingr 20 is adapted to receive any upward thrust upon the shaft i3; The construction coinprises ducts leading-troni one to the other oi the bearings lil-2G, together with means for causing a. circulation oi a suitable lubricant therethrough, but inasmuch as such lubricating means forms no part oi our present'invention it is not believed to be-necessary to describe it in det-ail herein.

Ellindicates a base-plate li''rorn which the rllhe upper end of the standard l() rises, such base-plate beingprovided with a central opening. They upper section 25 oi the Well tube is secured iu any suitable manner to the base-plate 24 below the central opening therethrough. and an elbouT discharge-member i6 is connected in` aniT suitable manner above the plate 24 so as to forni a continuation oi the well tube upon which is mounted in ant7 suitable manner the lower member 28 of a casing herein after more particularly described, vTo the rhe elbow outlet-member Q6 is. pro. vided with an upvvardly-eiitencllinp; sleeve 27 easing member :28 is connected oy means of screw-tl'ireads or in any otheil suitable manner the upper end of the uppermost shaft casing section 29 which extends downward through the sleeve 27 and through the well tube 25 about the shaft 13.

Qur improved coupling means for coupling together the several sections ot' the wellituliii-ng and the shaft casing comprises a spider 30 provided with an annular ring portion 31 extending between the adjacent ends of the well tube sections Each section 25 of the well tube is provided with a collar 32 mounted thereon by means of serew-tlireads, the collars 3i). and thevring 31 of the spider 30 being tightly connected together by means of a plurality of bolts 33. rillie spider 3) also comprises arms 3a extending from the annular portion 3l to the hub portion 35, the outer ends of the arms 34 being beveled as shown in Fig. 3 so as to guide the spider into centered position relative to the lowermost one of the two connected well tube sections The hub 35 of the spider is provided with a lining 3G of Babbitt metal, or other suitable material, forming a bearing` for the bearing sleeve 37 mounted upon the shaft 13, the sleeve 37 being held in position upon the shaft 13 by means of a pin 38. The adjacent sections of shafting 13 are connected together by means of a coupling 39 of any suitable type.

Mounted upon the lower end of the shaft 13 is a plurality of runners or propellers 40 of anysuitable type adapted to operate in suitable pump casings ell, also of any suitable type. Below the lowerinost runner ai() there is provided a bearing l2 adapted to hold the shaft 13 against lateral movement, such bearing being inclosed in a suitable housing a3. rlChe shaft easing 29 is provided with a number of openings al therein at its ,lower end covered by a wire netting 45.

inasmuch as the runners, the pump easings, the bearing and the lower end of the lowermost section of casing 29 are formed and operate in precisely the manner set forth in the Patent, No. 1,149,633, above referred to, it is believed to be unnecessary to further describe them herein. A pipe -lG is provided communicating with the uppermost section of shaft casing Q9 for the purpose of supplying water to the shaft easing for lubricating the bearings of the shaft before starting the pump in operation, as is set forth in our said patent.

Cuir improved liquid balaneiir 'neans comprises a easing member l? suppe ted by the casing member 2S, the easing member el? being provided with a downward exten sion 48 adapted to have suit-able packing means placed therein about ,the shaft 13, such packing to be held in position by an adjustable gland 49. A, plate 50 adjustably fixed upon the shaft 13 overlies the upper edge of the casing a?, having a stepped engagement with the said casing. A easing member 5.1i'i cooperates with the casing member 28 to inclose the plate 50 and the casing member a7. An outlet pipe ,52 leads from one side of the casing Z3-51.b An inlet pipe 53 communicates with a duct 5a formed in the wall of the casing member 23 communicat-ing through a suitable opening in the bottom of the casing 47. The arrangementy is such that water under pressure admitted through the pipe 53 from any suit-able source of supply presses upward on the plate or piston 50. Then the pressure within the casing 47 reaches a certain maximum, the plate or piston. 50 with the connected shaft 13 will be raised slightly so as to permit a film of water to escape between the upper edge of the casing a7 and the engaging face of the said plate or piston, the pump shaft being caused thus to rotate on a film of water, materially reducing the friction and improving the operation of the pump.
